Dynaudio North America, Inc. introduces the Octave Audio Jubilee Mono Final energy amplifiers
FOR IMMEDIATE RELEASE: Northbrook, IL – December 19, 2023
Dynaudio North America, Inc.importer and distributor of Octave Audio of Karlsbad, Germanyproudly introduces the brand new crown jewel of the Octave product lineup: the Jubilee Mono Final mono energy amplifiers.
From its inception in 1998, Andreas Hofmann’s Octave Audio Jubilee Sequence got down to outline what was potential in state-of-the-art tube electronics. Combining a high-precision tube achieve stage with a discrete semiconductor output buffering stage in a posh zero-feedback circuit, the Jubilee Preamplifier set a brand new commonplace with its exact and completely beguiling sound. As a lover of large-scale classical music, Hofmann knew he wanted to design a partnering Jubilee energy amplifier to be immensely {powerful} to cowl the dynamic swings of an orchestra or opera soloist, however refined and delicate sufficient to ship all of the emotion, nuance, and wonder dwell music evokes. In 2003, he realized this preferrred accomplice by the Jubilee Mono energy amplifier. Drawing from an octet of output tubes and Octave’s superior pentode design, it delivered 250wpc with refinement, energy, and authority into practically any loudspeaker load, enormously abetted by the Jubilee Mono’s huge energy provide and Octave’s unique Energy Administration system. The provision of a brand new, higher-power output tube, the KT120, noticed Hofmann again to the drafting board, and in 2014, the 400wpc Jubilee Mono SE was launched to crucial acclaim. In 2019, these fashions had been joined by a novel, fashionable tackle the venerable 300B SET amplifier, the 30wpc Jubilee 300B mono amplifiers, which, amongst different issues, makes use of an Octave-designed 7Hz energy generator to instantly energy every 300B filament heater to eradicate hum and noise that steadily plagues such SET designs.
The brand new Jubilee Mono Final represents the end result of over 20 years of continued analysis and improvement and is way more than merely the evolution of the Mono SE. Jubilee Mono Final effortlessly develops 440wpc utilizing new KT170 energy tubes, nonetheless the first story that makes it extra revolutionary than evolutionary is in its use of recent, proprietary circuit and transformer applied sciences. Among the many quite a few enhancements over the Jubilee Mono SE, the Jubilee Mono Final encompasses a newly-designed driver stage, a brand new, devoted output tube filament heater energy transformer, and a brand new, huge output transformer design that successfully will increase secondary winding floor space by 50% whereas decreasing distortion-inducing pores and skin impact to vanishing ranges. These developments and enhancements work in concord to carry an enormous enchancment in efficient energy bandwidth (10Hz – 100kHz), far superior section precision, and enormously elevated dynamic vary with out the standard accompanying rise in distortion. Sonically, this all provides as much as a particularly powerful-sounding amplifier with seemingly limitless extension and backbone on the frequency extremes, however with the pure and unfettered midrange one would count on from probably the most delicate tube electronics. In a single phrase: breathtaking.
